LGGIKIR'G: DEVICE.

application filed septcmber T 0 all whom it may concern Be it known that I. Eovvnnu new, a citizen of the United States, residing at Provi dence, in the county of Providence and State of Rhode Island, have invei ted certain new and useful improvements in Loching- Devices, of which the following is a specification. Y

My invention relates to devices for clamping and locking articles or parts of various kinds.

The essential. objects security against theft; upon articles of various thickness; security; simplicity of operation; compactness; and inexpensiveness at construction.

To the above ends essentially my invention consists in such parts and in such coinbinations of parts as "fall Within the scope of the appended claims".

adaptability for use In the accompanying drawings which form a part of this s ecitication,

l igure 1 is aperspective view of my locking device applied to hereof a spare automobile tire, the latter being shown broken away Figure 2, a partial section on lcig rc 1 Figure 1*. re 2, and

Figure ure 3.

like reference characters indicate like parts throughout the views.

My locking device is conjunction with a spare tire carrier of an automobile wherein 7 is the supporting ring, 8 the telly, 9 the tire; 10 the fixed plate and 11 the movable or clamp plate 12 the novel line-2- 2 of 3., a section on line 3-43 of Figsection on line 4- 1 of Fig attaching pin. and 13 the nut thereon, all as usuah The two plates have registering holes 1%" which usually accommodate the hinged member of the padlock.

My structure includes a bolt 15 comprising a shank 16, and a cylindrical fixed hea 17. The end of the shank is preferably beveled at one end as at 18, and is provided with a screw thread 19. In its threaded area is a radial recess .20. The head 17 is loosely seated in a circular cavity 2-). in a disk or collar 23 whose central opening 24; admits the shank upon which it is rotatable. The outer face of the head 17 is thus flush with the outer face of the disk 23.

A not 26 of special construction is provided. This is a cylindrical housing comprising a back 27,

ot' my invention are the retaining inem- 1 tends to. a. lrey opening 56 described herein in d ed end of the bolt 11, 1922. Serial N0. 587,272.

a side 28, and a face plate 29. The plate is fixed to the side in any convenient manner, in this case by a rod 31 riveted in the face and back; The back is provided with a central opening 33, and with an in ternal hub 3% extending to the face plate. The opening in the back and the bore of the hub are provided with a thread 35 adapted to receive the thread 19 of the bolt. The hub has at opposite points in its side perforations 3'7 and 38.

A crescent shaped plate l0 comprises a body portion a1 with tapering end portions or arms 4:2 and d3. This plate constitutes a broad lever provided in the center of the body with a hole e5to loosely receive a pin 26 riveted in the front. and back of the housing and serves as a pivot pin. The arm 42 has fast thereto a pin 48 adapted to e.(- m tend loosely into the recess 20. The arm 4:?) has a slot 50 into which extends a. pin 51 Whose inner end is fast in the perforation 38 oi the hub. A helical spring 53 surrounds the latter pin and has its ends pressing w against the hub and the arm 48. This spring normally retains the pin 48 in its recess 20.

A key post 55 fast in the back plate exin the lace plate adjacent the arm A key 58 has a recess 55, 59 to permit application to the key posts; and. the lug or foot 60 of the key is when inserted into the housing, in the path of the arm 42 and serves to elevate the arm- 42 and thus removes the pin $8 from its recess. this instance there is provided a key plate 62 having at one end lateral. lugs 63 riveted in the. back and face plate of the housing; for the purpose of attachment. This plate has a slot 65 for portion 60 to the lever.

In operation the shank 1 1 of the bolt is passed through the opening in the parts to be looked as .hown, with the disk 23 abutting against one member.

the niemb'erQG is screwed, thus drawing the head 17 into its seat, and tightening the disk and housing upon the members to be locked. During the screw- 111g operation the pin 4-8 is key 58 until the recess 20 is reached, whereupon the'ltey is turned and the spring 53 forces the-pin into locked position.

It is obvious that changes in details of construction within tion may be made. The description of the device has been gi en in detail merely for the admission of the key Upon the threadelevated by the the spirit of my invcnthe opposite Sit.

(:leerness of understanding and no undue limitation should he understood therefrom.

I claim 1. In it deiire or the character set forth, a bolt provided with a screw thread, a housing provided with a. hub having a threaded opening adapted to receive the bolt, and with a key hole, a vibratory lever yieldingly mounted in the housing transversely of the hub comprising an arm at one side of the bolt adjacent the key hole. and an arm at le of the bolt, and a projection on one arm engagenble with the bolt.

2. In it device of the character set forth,

e bolt comprising a. shank and 21 head, a

collar loose on the shankprovided with a rarity loosely enclosing the head, a housing provided with an opening to receive the bolt and with a key hole, e vibratory lever yielding-1y mounted in the housing comprisingan arm at one sideof the bolt adjacent the key hole, and an arm on the opposite side of the bolt, and a projection on one arm engageable with the bolt.

3. In a device of the character set forth a. bolt, ahousing provided With an opening adapted to receive the bolt, and with a key hole, a vibratory lever yieldingly mounted 1n the housing comprising arms extending to opposite sides of the bolt, a projection on one arm adapted to engage the bolt, and a key plate in the housing intermediate the last mentioned arm and the hole.

In testimony whereof I have afilRed my signature.

EDWARD ROY.
